For the sherry vinaigrette: Peel the oranges with a sharp knife. Remove the segments by cutting between the white membrane of each segment. Squeeze out the 2 tablespoons of juice and reserve. Combine the olive oil, vinegar, juice and mustard together. Season with salt and pepper and whisk vigorously. Finish with a squeeze of lemon juice.
For the kale salad: Remove the tough stems from the kale and discard. Finely slice the leaves into thin ribbons and toss together with the cranberries and vinaigrette. Serve on a platter scattered with orange segments and sprinkled with the almonds.
